Application y filed May 2,

1 My invention relates to harvesters and more particularly to .an improved cutting and gathering` mechanism for the same.

One of theobjects of the present inven- 5 tion is to provide a floating cutting mechanism adapted for use in connection with a harvester platform. 'y f A furtherobject--is to provide an improved cutting mechanism which will lcut close t the ground in amanner to follow irregular surfaces of the ground independently of the harvester platform. p Astill further object is toV provide a gathering means to cooperate with my improved cutting mechanism in a mannerto convey thecrop cut by said cutting mechanism to saidplatform. j These and other objects are obtained by providing a construction and an arrangement ofthe various parts in the manner` hereinafter described and particularly point- `ed out in the appended claims.

Referring to the drawingsp Fig. 1 isa top plan view of a harvester showing my improved cutting mechanism embodied therein; L Fig; 2 is a cross-sectional view taken ony the line 2-2 in Fig. 1 showing the manner in which my improved cuttingmechanism is pivoted to the underside of the harvester platform; and Y Fig. 3 is an enlarged fragmentary detail view showing the pivotal connection of the `cuttingV mechanism to the harvester platform. n Y

For the purposes of illustration, 1 have shown my improved cutting and gathering mechanism embodied iny a harvester comprising the usual main frame member 5 ad-` 40* justably mounted on the main or traction wheel 6 by means of a` bracket?. The harvester is provided with the usualv tongue 8 and supplemental draft members 9. Extending laterally from the main vframe 5 and secured thereto by means of bolts are plat-- form supporting `frame members 10 and 11, Extending longitudinally ofand secured to the platform supporting` members 10 and 11 are other platform frame members 12 and 13. Secured to the rear of theplatform supporting member 10 are transversely eX- tending wood bars 14 and 15. Secured to and mounted on the platformr` supporting members 10, 11, 12 and 13 is a quadrantalr platform 16. Adjustably supporting the mechanism to follow depressions or irreguiaas. semi No. 636,035.l l

grassward end of theplatform 16 is a grain wheel-17. Any well known adjustable mechanism 18 may be cmploycd'for adjustingl the platform 16 on the grain wheel 17 relative to the ground. Y f` i F or the purposes of illustrating my .invention, I have shown agathering mecha- `nismof the horizontal revolving` four-arm ltype but` it will be understood, of course, that any form of gathering mechanism, such for a instance` as a revolving reel or reciprocating rake, may he employed.` The construction nere employed comprises aJ rake 19 secured to an arm 20 mounted in 4anarm socket 21. The arm socket is pivotally mounted in a rei ".0 volving disk 22. d-Thile I have only shown one of these arms. it will be understood that four of these arms are positioned at right angles with respect vto each other.` The mechanism for driving these arms ycomprises'75 Y a gear 23 fixed tothe disk 22 and in mesh with a pinion 24 which is secured to a shaft 25 journaled in the-v main frame 5. Secured to the rear end of the shaft 25 is abeveled gear 26 which initurn is operatively driven by a beveled pinion 27. The pinion 27' is .fixed to a shaft 28 rotatably mounted inthe main frame 5. The stubbleward end of the shaft 28 has secured thereto a gear 29 which in turn is operatively driven by a main'drive gear 30 secured to the tractiontwheel 6 of the harvester. The mechanism thus de-. scribed is the power drive mechanism ordinarily employed in driving the gathering mechanism in thistype of a harvesterand this construction 'per se Vdoes not form any 'partof the present invention. u 'y y f.

My improved floating cutting mechanism comprisesa cutter bar 31 provided ywith the usual knifev guards 32 spaced at regularxintervals throughout the length ofthe cutter Secured to the rear of the cutterbar 1s an angle member 38. f

The mechanism which permits the cutting larities on the surface of the ground independently of the position of the platform 16 of the harvester, comprisesA forwardly eX- tending arms 34; pivoted at 35 to brackets 86 secured to the wood bars 14 andl. The forward ends of the arms .34.* are secured to the cutting mechanism by means of bolts`37. The rearward ends of the arms 34 are provided with upwardly turned portions 38. These portions 38 are turned substantially wheel 45.

at right `angles to the main body portion of the 'arms 34 and are provid-ed with apertures 89 which are adapted to receive a Apin 40. The cutting mechanism is balanced or resiliently maintained in the floating position shown in Fig. 2 by means of adjustable extension springs 4l having their forward ends connected to the pins 40 and their rearward ends adjustably connected by means of bolts 42 to the platform supporting` member ll. Operatively mounted on the cutter bar '31 and extending into the guards 3Q is the usual'reciprocating knife The knife 43 is driven'by areciprocating pitman connection 44 which in turn derives its power from tlv- The ily-wheel 45 is operatively driven by a shaft 46 which in turn is driven by the shaft 28 through the medium Vofthe beveled gear and pinions 4? and 48 respectively.

In *the operation of the above described device, it will'be understood that the platform ,may be adjusted on the main wheel o and on Vthe grain wheel l? to any desired position but preferably to the .position in which the cutting mechanism rests upon the ground. Then as the harvester is drawn over the ground and irregularities m the surface of the ground are encountered, the 'dei-- ibi'lity of the cutting mechanism, by reason of its pivotal-connection to the platform together with the -resilient spring connections 41, will permit the cutting` mechanism to yield in a manner to conform tothe surface of the ground independently of the position or movement of the platform. As the crop is cut by the floating cutting mechanism, the `raking mechanism 19 of the revolvinggathering mechanism will convey the crop from vthe cutter bar to the platform where it is conveyed by means of the said raking mechanism through substantially an angular Vdistance of l90 degrees and deposited at the yrear of the harvester.

`While l have illustrated and described my improved :floating cutting mechanism used in connection with this type of harvester, it will be understood that the same is capable of use with any type of platform or gathering mechanism in which it is desired to have the cuttingmechanism cut the crop close to `the ground independently ofthe position of the platform.

In the above specification, have described 'my invention in the form shown herein but itv will be understood that the same is capable of modification and thatmodification may be employed without departing` from the spirit and scope of the invention as eX- fp-ressed in the following claims.

"What I claim as my invention and desire 'to secure by Letters Patent is:

Q. ln a harvester, the combination of a frame, a platform thereon, 'a cutting mecha.- nism, and a pivotal and resilient connection beneath the glatform fo" floatingly mounting the cutting mechanimn on the frame.
